MACKENZIE TROOPS MEMORIAL Among the many U.S. flags displayed in the Spur Cemetery this week is one honoring soldiers in the nineteenth-century Indian Wars campaigns on the Texas plains: “In Memory Of Private Gregg, William Max, W. H. Kilpatrick and other soldiers who met death in this region while serving under General R. S. MacKenzie, Fourth U.S. Cavalry, 1871-1872 and 1874-1875,” reads the 1936 Texas Centennial Marker.
